Abstract: A milling tool for roughing workpieces is provided with a plurality of cutting flanks and flutes disposed in between. The cutting flanks are provided on the cutting side with a predetermined rake angle, and the cutting edges have moreover a profile of wave form that extends over the width of the cutting flanks. The profile of wave form is provided with a bevel having a width corresponding to at least the height of the crest, and having a wedge angle that is more obtuse than the wedge angle of the milling tool. When the tool is subjected to heavy operational demands, a chipping or breaking off of the crest edges is thereby prevented, thus increasing the service life of the tool.

Abstract: In a process for deburring edges on an object, for example the cutting edges (14) of a cutting tool (12), a fluid guided under high pressure through at least one nozzle (26) in the form of at least one fluid jet (28) is directed onto the edges with a speed sufficiently high to separate the burrs. A device for deburring the edges (14) of an object (12) with an axis of rotation (z) has a clamping means (16) for temporary clamping of the object (12) to be deburred and at least one fluid-carrying nozzle (26) arranged transverse to the axis of rotation (z) and aimed at the object (12), where the nozzles (26) and/or the clamping means (16) are designed to perform a rotational movement about the axis of rotation (z). Deburring is carried out carefully and without damaging or rounding the edges.

Abstract: In a modular system (10), with a holder part (12) for clamping in a spindle of a turning machine and a machining tool (14) attached interchangeably to this, the machining tool (14) has a hollow cylindrical shaft part (18) which overlaps a receiving mandrel (20) on the holder part (12) and is fixed to the holder part (12) by means of a screw device (28, 30) mounted on the holder part (12) and generating a tension or compression force via a tension or compression rod (22) running through the holder part (12) and the receiving mandrel (20). The end of the tension or compression rod (22) facing the machining tool (14) is expanded and under the effect of the tension or compression force leads to an expansion of the receiving mandrel (20) such that the peripheral surface (42) of the receiving mandrel (20) and the inner surface (44) of the shaft part (18) are clamped against each other to form a friction connection.
